Make A Projected Solar Eclipse Image Through A Pinhole

Ideally, you will have snagged some authentic top of the line Solar Eclipse Glasses by the time it comes to the USA in a little over a month. But, in case you don’t, here is an interactive way to view and project the eclipse safely.

Taking nothing more than two pieces of card or paper and creating a pinhole in the center of one, you can project a replica of the totality right in front of your eyes. But seriously, try and find some safety glasses so you can enjoy it without obstruction.

Here are instructions for the “projected” future:

DIY: Simple Card Projector

The simplest and quickest way to safely project the Sun is with a projector made from only 2 pieces of card or paper.

You Need:

  • 2 pieces of stiff white cardboard, e.g. 2 paper plates
  • alternatively, 2 sheets of plain white paper
  • a thumbtack, a sharp pin, or a needle

What to Do:

  1. To make a quick version of the pinhole projector, take a sheet of paper and make a tiny hole in the middle of it using a pin or a thumbtack. Make sure that the hole is round and smooth.
  2. With your back towards the Sun, hold 1 piece of paper above your shoulder allowing the Sun to shine on the paper.
  3. The 2nd sheet of paper will act as a screen. Hold it at a distance, and you will see an inverted image of the Sun projected on the paper screen through the pinhole.
  4. To make the image of the Sun larger, hold the screen paper further away from the paper with the pinhole.

box projector works on the same principles, it requires a little more time and a few extra items to construct, but it is more sturdy.

Keep Safe!

  • Never look at the Sun directly without protective eye gear. Even sunglasses cannot protect your eyes from the damage the Sun’s rays can do to them.
  • Always keep your back towards the Sun while looking at a pinhole projection.
  • Do not look at the Sun through the pinhole.
